If you find it annoying, you’re not alone.
Glare is also an important workplace hazard that shouldn’t be lightly dismissed since it can trigger work inefficiency and eye fatigue. There are four types of glare that we should be aware of.
First, direct glare is a form of glare that comes directly from the light source, especially one poorly positioned, resulting in high light levels in one’s field of view. An example of direct glare in the outdoor environment is when the sun’s brightness, which is too much for our eyes to adjust to, causes discomfort and temporarily blinding. On the other hand, at the workplace, light from the monitor can cause glare if brightness and contrast controls are not properly adjusted. Also, high intensity light coming from unshaded light fixtures is another source of direct glare.
The second type of glare you may be more familiar with is reflective glare. This glare, taken literally, results from very bright reflections of light, usually reflected from a glossy or polished surface. Sun light reflected from water or sand at the beach is a type of reflective glare. People who frequent the outdoors in the summer are advised to wear polarized sunglasses that shield the eyes from this high intensity glare. At the office, desks and monitor screens can reflect overhead and task lighting into your field vision causing reduced visibility and discomfort.
The last form of glare, discomfort glare, is caused by excessive luminance in the field of view resulting in annoyance and sometimes a painful sensation
To ensure your work place is comfortable, you’ll want to find a suitable overhead lighting that is not too piercing for regular tasks. Consider dimming if your eyes can’t adjust to the high brightness. In the afternoon, you may want to pull down window blinds to shield your eyes from the direct glare of sunlight. Also be sure to have sufficient and good lighting, reflective glare and contrast glare from your screen can be avoided by buying good desk lamps that provides even illumination across the monitor and the desk surface.
